“Since President Trump took the oath of office, the Trump Old Post Office, LLC appears to be in breach of the plain language of the lease agreement,” the letter read, in part.

U.S. Senate Committee on Homeland Security and Governmental Affairs Ranking Member Claire McCaskill, D-Missouri, and Permanent Subcommittee on Investigations Ranking Member Tom Carper, D-Delaware, sent a letter to General Services Administration Inspector General Carol Ochoa requesting a review of GSA’s management of the lease with the Trump Old Post Office to develop and manage the Old Post Office Building in Washington, D.C.

“Since President Trump took the oath of office, the Trump Old Post Office, LLC appears to be in breach of the plain language of the lease agreement,” the letter read, in part.

“Despite the warning signs from members of Congress and ethics watchdogs, GSA chose not to take any action to address or enforce this provision of the lease or the other steps to mitigate the difficulties the lease creates for GSA and other government officials who oversee management of the agreement. Your office is in a unique position to review GSA’s management of the lease of the Old Post Office Building and identify any potential missteps.”

The senators reminded Ochoa that the GSA IG office has previously led reviews of matters of significance, including audits of the Public Buildings Service’s lease administration practices.
